Understanding the Relationship Between TSH and Hyperthyroidism
No, you cannot have high TSH but still hyperthyroidism.
TSH (thyroid-stimulating hormone) is a hormone produced by the pituitary gland that regulates the thyroid gland's activity. When TSH levels are high, it means the thyroid gland is underactive (hypothyroidism), not overactive (hyperthyroidism).
In hyperthyroidism, the thyroid gland produces too much thyroid hormone, which suppresses TSH production. Therefore, people with hyperthyroidism typically have low TSH levels.
